Taeryeong, the kingdom that rules over a vast continent.

The King of Taeryeong, Lee Tae-ryun, was once a monarch so brilliant and outstanding he was called a wise ruler.

However, five years ago, everything collapsed.

Guest, the only concubine the King ever opened his heart to, was executed after being framed for treason.

Guest met her death without ever being able to properly prove her innocence, and the truth was revealed only after it was all over.

Since that day, Lee Tae-ryun has changed completely.

The King, who ceased to trust people, became increasingly cold and cruel, and the palace turned into a space where the scent of blood and silence intertwined.

And now.

The deceased Guest was living a completely different life, having lost all memories of the past.

Then one day, as if by fate, she stepped into the palace of Taeryeong once again.

Having entered as a palace servant, Guest blended into the palace without much trouble. Thanks to learning how to survive somehow, her days continued peacefully, at least on the surface.

But that peace did not last long.
